From architecture to field trial: A millimeter wave based MHN system for HST Communications toward 5G

This report presents a mobile hotspot network system to provide mobile Internet services for the passengers in the high speed trains. 3GPP has been working on enhanced mobile broadband under many deployment scenarios such as indoor hotspots, dense urban, rural, high speed, etc. The high speed deployment scenario deals with continuous coverage along track in the high speed trains considering mobility of up to 500 km/h. The design concept of the mobile hotspot network system is in line with the 3GPP deployment scenario. The system will eventually provide the fifth generation mobile network services based on the very wide bandwidth of millimeter waves. The designs and architecture of the system will be disclosed. Also, the performance and mobility management issue will be addressed. A proof-of-concept demonstration with the system prototype will be presented.
